A computer hacker who calls himself "The Jester" claimed responsibility for the cyber attack which took down the WikiLeaks site Sunday, shortly before it started posting hundreds of thousands of classified U.S. diplomatic cables.
The Jester, who describes himself as a "hacktivist for good," said he took the controversial site down "for attempting to endanger the lives of our troops, 'other assets' & foreign relations."

He normally attacks Islamist websites, announcing "TANGO DOWN" on his Twitter account when claiming to have attacked a site. "Tango Down" is Special Forces jargon for having eliminated a terrorist.
